4 Claims. (CI. 37-42) The present invention relates to thrust bars for snow removing mechanism and particularly to such mechanism adapted for use in removing snow from streets and highways. It is concerned 5 more particularly with such mechanism which is carried by a motor truck.

This application is a division of my application S. N. 95,688, filed August 12, 1936.

In the past, the usual practice in the production of snow removing mechanism has been to mount the same permanently on a special truck. Such an arrangement is comparatively expensive, and its expense is increased because it can be used only during a short period of the year.

The advantage of the use of trucks as compared to tractors is that such devices can move easily from one place to another as required at a high rate of speed, which is almost a necessity.

The primary object of the present invention is 30 to provide power driven snow removal mechanism of a practical and eiilcient type which is arranged so that it can be readily mounted on. and removed from a truck. Both the snow remover and the power unit for driving the same 25 are easily and readily demountable. In this manner, the mechanism may-be applied to a standard truck, which is used during the snow season to carry the snow removing mechanism, and may be used during the remainder of the year 30 for hauling purposes as a freight vehicle.

Still another object of the invention resides in the provision of a novelthrust bar for resisting rearward movement of the lower end of a snow remover, this bar comprising members under ten- I 35 sion and under compression so that a light and simple structure of considerable strength is provided.

A further object of the invention is to provide a thrust bar which will transmit the force of the 40 snow to the frame of'the supporting vehicle, and not to the axles. This is particularly important in a snow remover which is mounted on the frame of the vehicle and which is so arranged that it is entirely carried by the frame. 45 'Another object of the invention is to provid in a vertically movable snow remover having means to guide the snow remover in a straight vertical line, an adjustable thrust bar so arranged that the position of the plow perpendicular to 50 the road may be secured.

Further objects and advantages of the invention will appear more fully from the following description, particularly when taken in conjunction with the accompanying drawings which form 55 a part thereof.

In the drawings:

Fig. 1 is a side elevation of a snow remover embodying my invention and shown as mounted on a truck.

Fig. 1a is a continuation of Fig. 1, showing the 5 power unit on a truck.

Fig. 2 is a detail showing ofthe rear end 0! the push bar support.

Fig. 3 is a top plan view of the thrust bar arrangement.

Fig.4 shows in side elevation a modified form of push bar.

As shown in Fig. 1, the snow remover is mounted on a truck A of any standard type. This truck has a chassis consisting of longitudinal members 2, and a front cross member. .The chassis is mounted on wheels 8, supported by axles such as the front axle Ill. The wheels, preferably the rear wheels, are driven by a motor mounted in the hood I2 and provided with a radiator M, The truck also has a cab it of any suitable type.

Mounted on the rear end of the truck is the power unit B adapted to drive thesnow remover through shaft D. v

0 indicates in general the snow remover. 11: consists in the preferred form of a casing having side walls, a bottom wall, and a rear wall. An opening in the rear wall communicates with the interior of a fan casing in' which is mounted a' fan for ejecting snow through the spout 48. Within the casing are mounted three augers or conveyers 50 on horizontal vertically spaced axes. These angers are all driven to feed snow towards the center of the casing so that it can pass through the opening into the fan casing.

The mounting of the snow remover on the truck will now be described, but for a more detailed explanation reference is made to applicants above mentioned application Serial No. 95,688.

The snow remover is carried by a suitable 40 frame. I provide a unitary carrier frame which may be easily applied to and removed from a truck for carrying the snow remover and the mechanism for manipulating the same.

The supporting and guiding arrangement for the plow includes vertically arranged T-shaped rails H4 and guide blocks or slide members H8 provided with T-shaped'slots fit over the arms of the T rails. Thus the blocks H8 are guided thereby for vertical sliding movement. Pins I22 connect the blocks I I8 and the plow frame. Thus the plow frame is guided at both sides for straight up and down movement.

For raising and lowering the plow a special hydraulic arrangement is provided. Hydraulic cylinders I88 are mounted one on each side of the snow remover, in which are slidably arranged pistons I38.

Secured to the vehicle at points to the rear of the front end thereof are uprights I48, which,are'

braced by links I42 connected at one end to the uprights and at the other end to the vehicle. Pivoted to the upper end of the uprights are beams or links I44, preferably I beams. These beams carry blocks I48 to which are pivoted the pistons I38 and links I48 which at their other ends are traversed by the pins I22. I

Of course one of these lifting devices is provided on each side of the plow. It will be noted that this provides a simple and convenient mechanism for raising and lowering the snow remover without blocking in any manner the front of the radiator of the truck. Thisis a special advantage since when such trucks are in operation there is danger that the engine will become overheated if the radiator is blocked.

The hydraulic cylinders I36 are supplied with fluid under pressure in any suitable fashion.

In order to brace the bottom of the plow against backward tilting because of the pressure of the snow, 8. special type of thrust bar which forms the object of the present invention is provided. A plate I14 is bolted or otherwise suitably secured to the chassis frame. This plate has a transverse wall I16 in which is threaded a lockable bolt I18. The plate is also provided with two horizontal slots I80. A bracing arm I82 extending diagonally downward from the plate has its end bent over into a parallel position, and carries a cross plate or stop I84 at its end to be engaged by the screw I18. Two bolts I86 are arranged at the end of the bar I82 and pass through the slots I80.

By this arrangement the position of the brace may be adjusted longitudinally of the truck, and it may be locked in any adjusted position.

A tension member I 88 is pivoted on one of the longitudinal chassis frame members and extends substantially vertically downwardly. The lower end is connected by a pin I98 to the end of the brace I82. Also pivoted on the same pin is a thrust bar I82 consisting of an I beam. The front end of this thrust bar is secured by a pin I84 to the lower corner of the plow supporting frame. Obviously one of these bars is arranged on each side of the snow remover, and the bracing members I82 are connected by a cross member I15 extending beneath the truck.

Fig. 4 shows a modified form of push bar, in and a second tension which the brace I11 is bent, member I19 pivoted to the chassis member 2 and to an intermediate point of the brace is provided.

While I have described herein some embodihicle. snow remover, said means comprising a thrust except within the scope of the appended claims.
